[0002] The roadbed is the basis of the pavement, and is also the basis of guaranteeing the pavement stability, and the quality of the roadbed construction quality will directly affect the pavement construction quality, even the comfort, safety and pavement service life of driving and other aspects. In high fill roadbed construction, due to the high filling height, the stability requirement of the roadbed slope is more stringent, and the roadbed backfilling soil material should have good water permeability, such as gravel soil, sandy soil and the like. In order to ensure the rolling effect and improve the compactness of the high fill roadbed construction, the method of layering paving should be selected, and after paving, compaction is carried out, and the compaction equipment proceeds in the longitudinal direction along the road, and compacts in the roadbed construction.

[0003] The existing compaction machine or equipment is provided with a scraper on one side of the compaction roller during use for scraping off impurities such as soil, but the scraper is usually fixedly arranged, and the soil and part of the stone particles and other impurities on the compaction roller directly rub and scrape the scraper, which easily leads to the wear and damage of the edge of the scraper. In addition, the scraper needs to bear the rotating torque from the compaction roller and the impact force from the material during the working process, which easily leads to deformation, fracture or falling off of the scraper. For example, the patent announcement No. CN219824816U discloses a roadbed compactor, which comprises a road roller main body, a bearing frame, a lifting adjusting frame and a protective cover.

[0032] The mounting plate 15 is mounted with a spring supporting piece for supporting the mounting bracket 22 to stably float.

[0033] The extension frame 14 is mounted with a scraping piece for cleaning the annular outer wall at both ends of the compacting roller 13.

[0034] In the embodiment, the equipment main body 11, the mounting frame 12 and the compacting roller 13 work cooperatively, the roadbed is compacted during movement, and the roadbed forming is promoted, the compacting roller 13 rotates, and the rubber wheel 23 is also driven to rotate, so that the cleaning roller 18 is driven to rotate, the cleaning roller 18 cleans the impurities on the surface of the compacting roller 13, or the rubber wheel 23 is stationary, and the cleaning roller 18 is not affected during cleaning.

[0035] During movement, the rotating torque generated by the compacting roller 13 during rotation and the impact force of impurities and the like are transmitted to the cleaning roller 18 and the rubber wheel 23, the mounting bracket 22 can float, the mounting bracket 22 rotates and extrudes the spring telescopic rod 26, the spring telescopic rod 26 plays a buffering role, and the direct friction and scraping of the cleaning roller 18 and the rubber wheel 23 are reduced.

[0036] The horizontal position of the mounting plate 15 can be adjusted according to requirements, the cleaning roller 18 can be effectively cleaned, and the scraping piece can clean the annular outer wall at both ends of the compacting roller 13.

[0037] For example Figure 2 and Figure 4As shown, in another embodiment, the limiting member includes a limiting bolt 19 threadedly connected to the extension frame 14, and both ends of the mounting plate 15 are provided with a plurality of limiting holes 20 that cooperate with the limiting bolt 19.

[0038] After the mounting plate 15 is slidably adjusted to the desired position, the limiting bolt 19 is aligned with the corresponding limiting hole 20 and screwed into the limiting hole 20 to fix the sliding position of the mounting plate 15.

[0039] like Figure 4 As shown, in another embodiment, the top of the mounting plate 15 is connected to two sets of T-shaped strips 21, and the bottom of the extension frame 14 is provided with a T-shaped groove for sliding the T-shaped strips 21; the mounting plate 15 can be slidably adjusted to a horizontal position, and the position of the mounting plate 15 can be adjusted according to actual needs, i.e., the size of the compaction roller 13, so that the cleaning roller 18 and the rubber wheel 23 contact the compaction roller 13.

[0040] In another embodiment, the spring support includes a connecting plate 25 and a spring telescopic rod 26 rotatably connected to one side of the connecting plate 25.

[0043] In another embodiment, the rotating shaft is rotatably engaged with the mounting bracket 22, and a cleaning brush is connected to the outer wall of the cleaning roller 18;

[0044] While the cleaning roller 18 is rotating, the cleaning brush can clean and remove impurities from the surface of the compaction roller 13.

[0045] In another embodiment, the scraping component includes a fixing frame 16 and a plastic scraper 17. The fixing frame 16 is fixed to the top of the extension frame 14 by bolts, and the plastic scraper 17 is bolted to one end of the fixing frame 16 near the compaction roller 13, and the plastic scraper 17 is inclined.

[0046] The fixed frame 16 is fixed on the extension frame 14, and the plastic scraper 17 can scrape and clean the corresponding position of the compacting roller 13 corresponding to the rotating shaft and the rubber wheel 23. The length of the plastic scraper 17 is small, which reduces the probability of breakage, facilitates replacement, and reduces the overall loss of the equipment.

[0047] During the construction of the roadbed, the construction preparation is done, and then the filler is selected. It is appropriate to use well-graded coarse-grained soil, such as gravel soil and sandy soil, with a maximum particle size of less than 15 cm. It is not appropriate to directly use silt, strong / middle / weak swelling soil, and soil with excessive standard of easily soluble salt. It is not appropriate to use humus soil and miscellaneous fill. When the liquid limit of fine-grained soil is greater than 50% and the plasticity index is greater than 26, it is not appropriate to use it as the construction material for high fill roadbed construction.

[0048] During the construction of the roadbed, the surface of each construction layer should not have accumulated water. The fill roadbed should have a drainage cross slope of 2% to 4% according to the soil conditions and construction climate conditions to drain rainwater to the temporary construction drainage ditch. The longitudinal and transverse slopes of each layer of the roadbed in the excavation construction should be reasonably determined according to the shape of the cross section of the roadbed and the size of the route longitudinal slope to determine the length of the roadbed excavation section and the construction method, so that the rainwater in the excavation section is drained to the outside of the roadbed through the temporary drainage ditch in a timely manner.

[0049] To ensure the rolling effect and improve the compactness of the high fill roadbed construction, the method of layering and paving should be selected, and the thickness of each layer should not exceed 40 cm. During the construction process, after the backfill material is unloaded to the specified location, the material is leveled by bulldozing. For positions that cannot be reached by the bulldozer, manual paving should be used to ensure the uniformity of the entire highway soft foundation high fill roadbed paving

[0050] The device main body 11, the mounting frame 12, and the compacting roller 13 work together to move longitudinally along the road direction. The movement for roadbed compaction is flexibly adjusted according to the on-site operation conditions to promote the formation of the roadbed. The compacting roller 13 rotates, which can also drive the rubber wheel 23 to rotate, thereby driving the cleaning roller 18 to rotate. The cleaning roller 18 cleans the impurities on the surface of the compacting roller 13, or the rubber wheel 23 does not move, which does not affect the cleaning of the cleaning roller 18.

[0051] During movement, the rotating torque generated by the rotating compacting roller 13 and the impact force of impurities are transmitted to the cleaning roller 18 and the rubber wheel 23, which can make the mounting frame 22 float. When the mounting frame 22 floats, it drives the contraction rod to press the spring. The contraction rod repeatedly slides under the elastic force of the spring, and the spring extension rod 26 plays a buffering role, reducing the direct friction and scraping borne by the cleaning roller 18 and the rubber wheel 23.

[0052] The horizontal position of the mounting plate 15 can be adjusted according to requirements. After the sliding adjustment position of the mounting plate 15 is adjusted, the limiting bolt 19 is aligned with the corresponding limiting hole 20 and is screwed into the limiting hole 20, so that the sliding position of the mounting plate 15 can be fixed, and the cleaning roller 18 can effectively clean, and the plastic scraping plate 17 can scrape and clean the corresponding position on the compaction roller 13 relative to the rotating shaft and the rubber wheel 23.

[0053] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
